    I just got done changing the fuel pump and sending unit on my 90 Blazer and now it won`t start, I don`t even hear the fuel pump come on when I turn the key on. it was running ok before I changed everything, but the sending unit was bad, so I did both while I had the tank out. I checked my fuses and I tryed another fuel pump relay and got nothing, is it possible to get a new fuel pump thats bad right out of the box ?.

    Check your ground first. I just got done changing mine on my Tahoe, not as bad a job as everyone says.

    Not an uncommon thing to have a bad part out of the box these days. It would have been a smart idea to test the pump first to see that it worked but oh well. I was going to suggest the fuel pump relay but you said you changed it already. Check the ground as was stated first before doing anything else.

    Ok im stupid, I went back and checked my fuses again thinking maybe I missed something, and I was right, the ECM-B fuse was blown, put in a new fuse and it started, im so happy I don`t have to pull the tank again. :D
